Simple Security System Using Logic Gates

I have complied this list from different resources.

Simple security system using logic gates.

6 bit password based security system using logic gates duration. It is the nature of an xor gate to output a high 1 signal if the input signals are not the same logic state. Digital logic design projects list with logic gates for beginners. 1 shows the circuit of the digital security system while fig.

This is a complete list of digital logic design projects for those who want to learn about digital logic circuit and want to design digital logic circuit for their project. 2 shows the proposed wiring diagram for the loops around the premises. The digital security system circuit. A burglar alarm system for a bank is to be operative only if a master switch at the police station has been turned on.

You can create a three input and gate by using two two input and gates for example. Security system using xor nor 1. Simple password lock system using logic gates digital system miniproject duration. Here the inputs for the various sensors placed on the home s.

It is an electronic circuit having one or more than one input and only one output. Subject to this condition the alarm will ring if the vault door is disturbed in any way or if the door to the bank is opened unless a special switch is first operated by the security guard s key. And gates can be used in a home alarm system. Output is based on the voltage on pin 5.

Dld project submissing to chowdhury akram hossain aiub. Also read the interesting post pull pin security alarm system. Before using this security system make sure that loops shown in fig. At the time when power supply is attached to the circuit pin 5 voltage is at zero as loop is unbroken.

A two input and gate is an electronic logic gate that has two inputs and one output. The output is high only if both of the inputs are high. Functioning of these circuits is very easy when we will receive. 1 4 bit password security system using nor xor.

Based on this logic gates are named as and gate or gate not gate etc. Ra r 5 447 views. The relationship between the input and the output is based on a certain logic. 2 are connected as shown in fig.

Again the purpose of the experiment is not to make a real security system but merely to introduce you to the principle of xor gate code comparison.
